forecast key messages:
* significant impacts associated with tropical storm imelda are
forecast to remain east of south-central texas
* nevertheless, some pockets of heavier rainfall could develop across
portions of south-central texas on Thursday
* should these pockets develop, some isolated locations could see
minor flooding concerns
* 1 to 3 inches of rainfall is possible along and east of u.S. 77 and
1 2 to 1 inch of rainfall west of u.S. 77 into the eastern hill
country. Isolated higher amounts are possible should any heavier
pockets of rainfall develop Thursday.

Short term (tonight through Wednesday night)
Tropical storm imelda made landfall near freeport earlier this
afternoon. Scattered showers in the outer rain bands have wrapped
into eastern areas of the cwa. Additional isolated showers and
thunderstorms could form through the remainder of the afternoon and
early evening, closer to the i-35 corridor, near the edge of the
tropical moisture plume and differential heating boundary. After
sunset convective activity is expected to diminish inland across
south-central texas, and contract toward the center of imelda and
within bands to the east and south of the center.

South-central texas will remain on the "drier" side of the system on
Wednesday, with the center of imelda remaining east of the cwa. We
have trended pops slightly downward for Wednesday across the i-35
corridor for Wednesday. However, with diurnal heating Wednesday we
should still see the development of scattered showers and a few
thunderstorms in outer bands across eastern areas of the cwa.

Long term (Thursday through Tuesday)
Thursday actually looks to be the best opportunity for rainfall
for some central areas of the cwa. As the remnants of imelda open up
to the northeast of the CWA it appears instability on the southwest
side of the system could interact with the tropical airmass and result
in some heavier convective feeder bands developing in an area of low
level moisture convergence over the region in the afternoon and
evening. Where these potential bands develop is highly uncertain, but
should they develop there could be some locally heavy rainfall,
given the tropical airmass, that could potentially lead to isolated
pockets of minor flooding.

A deeper southerly fetch develops across south-central texas on
Friday as the remnants of imelda pull move north of texas. Lingering
moisture in the area could result in streamer showers across eastern
areas of the CWA in the morning, working inland along the sea-breeze
in the afternoon. Weak, flat ridging builds over the area during the
weekend into early next week, with convective chances gradually
diminishing and limited to only isolated showers across the eastern
zones. Disagreements in global models with respect to the upper
level pattern develop into the middle of next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
